Ran "Hey mister, something's wrong with your car, it idles roughly" - number one comment I got in Israel when daily driving a 70 Barracuda with a lopey cam. Currently working on - 1966 Dodge A100 van 318/auto Finally - disc brakes on the front. In the plans - rear disc brakes, B&M 250 blower

At least on the '71-'74 B-vans you might get lucky and find the equipment tag still stuck to the underside of the hood. and hope you find "AZ1 LIMITED SLIP RR AXLE or SURE GRIP DIFF" listed.
